We are currently facing an NPrinting Designer issue after the latest Windows/Office update and are actively working to resolve this defect.
After attempting to open the NPrinting Template Editor in NPrinting Designer you may see this error message: “Qlik NPrinting Designer can't find a supported reporting template editor for this file…”
Thanks for the suggestions Digvijay and Paolo. I had already tried rolling back a month to Version 2108, so I tried rolling back further to Version 2012.
This fixed Nprint Designer, and I could then edit templates, BUT unfortunately then Word and Excel would only open in safe mode! I had to run online repair which took me back up to Version 2109!
So im back at sqaure one. I have Nprint designer working on one of the server consoles, so ill have to work on RDP untill we get an update / fix from Qlik.
